Spin correlations and quantum entanglement in $γ γ \to t t ˉ$ at polarized photon colliders with NLO QCD corrections

Jun Jiang, Zong-Guo Si, Han Zhang +1

We study spin correlations and quantum entanglement in the process $γ γ \to t t ˉ$ with the photons coming from Compton backscattered laser beam. We present predictions for the cro…

Study $γ γ \to τ^{+} τ^{-}$ process including $τ^{+} τ^{-}$ spin information in Pb-Pb ultraperipheral collision and at Lepton collider

Peng-Cheng Lu, Zong-Guo Si, Han Zhang +1

We study the $γ γ \to τ^{+} τ^{-}$ process including full $τ^{+} τ^{-}$ spin information in Pb--Pb ultraperipheral collision and at lepton colliders. We present the predictions for the corres…

Probing the electromagnetic dipole moment of the $τ$ lepton in the $e^{+} e^{-} \to γ^{*} / Z \to τ^{+} τ^{-}$ reaction

Peng-Cheng Lu, Zong-Guo Si, Han Zhang

High-precision measurements of the lepton's electromagnetic dipole moments provide a powerful probe for testing the Standard Model. A non-zero value of the $τ$ lepton's electric(we…

NLO EW corrections to tau pair production via photon fusion in Pb-Pb ultraperipheral collision

Jun Jiang, Peng-Cheng Lu, Zong-Guo Si +2

We study the next-to-leading order (NLO) electroweak (EW) corrections to the $γ γ \to τ^{+} τ^{-}$ process in Pb-Pb ultraperipheral collision (UPC). We find that the EW correction $δσ_{\…
